Thanks to the rise of intermittent renewable energy sources, we’ve seen increased demand for new energy storage technologies, like batteries, pumped storage hydropower, and flywheels. But what if I told you that this little toy, a 200-year-old invention, combined with thermal energy storage might be a promising solution? Let’s explore the Stirling Engine and the future of renewable energy storage.

Building large-scale renewable energy projects demands time, money, human capital, and risk tolerance. Most renewable projects would never be built without the involvement of third-party debt and equity investors. Understanding the essential assets, financial attributes and risks associated with renewables projects is prerequisite to an understanding of renewable project financing. It also provides insights into public policies, consumer preferences, economies of scale and other macro topics that will influence the future of renewables. With this overview in mind, we will address the following questions:

What are the most common types of financings available for utility-scale wind and solar energy generation projects?
At what points in a project’s life cycle do financings come into play?
What assets are necessary for these financings, and what economic incentives and considerations shape these investments?
What are “offtake agreements”, and what role do they play in a project’s operations and financings?
What is “tax equity financing”, and how do the federal “Production Tax Credit” (for wind) and “Investment Tax Credit” (primarily for solar) benefit renewable projects?

What are the macro drivers of new renewables investments, and what opportunities exist to expand renewables?

Renewable Energy 101: How Does Hydroelectricity Work?

Energy Efficiency No Comments »

Water — so essential to us all, and yet it still has the potential to further impact our lives in important and positive ways. Hydroelectricity goes by many names — “hydroelectric energy,” “hydropower,” or just plain “water power” — but don’t let that trip you up. It all boils down to harnessing the force of moving water. In this video, you’ll learn interesting hydropower facts and how water power works. Isn’t it amazing how something as simple as water can offer us clean, renewable energy to power our homes, businesses and communities sustainably? We certainly think so!


Renewable Energy 101

Water covers 71% of the Earth’s surface and is vital to our daily lives. It can also be a clean, renewable, reliable source of electricity.

Hydroelectric energy comes from capturing the force of moving water that’s in our Earth’s rivers and oceans. We do this by using the movement of the water to spin hydraulic turbines. That generates kinetic energy, which is converted to electricity through a generator and then sent to the power grid.

Most hydropower is generated from dams built on rivers and streams, often where there’s a big drop in elevation so gravity can help us out. Dams block the water’s natural flow and force it through a large pipe with the turbine and generator before releasing it back into the stream on the other side of the dam. Today, we know that dams — most of which were built before the 1960s here in the U.S. — can disrupt river ecosystems. There haven’t been many new hydro plants built in the U.S. in a few decades, but some existing dams are beginning to be tapped for their electricity-generating potential, and existing hydro facilities are being upgraded to be less harmful to plants, fish and wildlife. This helps us get the electricity we need by protecting the natural environment around us. Now that’s a win-win!

एक बात तो हम सब मानेंगे कि जीवाश्म ईंधन का इस्तेमाल जलवायु परिवर्तन की सबसे बड़ी वजहों में से एक है. लेकिन अकसर ये सवाल उठता है कि क्या अक्षय ऊर्जा पर निर्भर किया जा सकता है. अगर किसी दिन धूप ना निकले या हवा ना चले तो क्या होगा? जर्मनी में कुछ लोगों ने इन सवालों के जवाब खोजने की कोशिश की और इसमें सफल भी रहे.

Why China is Leading the way in Renewable Energy

Renewable Energy No Comments »

The renewable energy market has been booming over the past two decades. Earlier many countries perceived Renewable Energy Sources (RES) as a forced concession to environmentalists and did not believe in a prompt transition to “clean” sources. Now everything has changed.
In 2020, the European Union green generation left behind the coal and gas industries for the first time in history. The United States intends to increase its industrial-scale generation capacity by more than 30 GW (Gigawatts) in 21 years. Against this background, many people wondered who is leading the race for alternative energy today?
You are on the Innovative Techs and right now we will go over how China became the “green dragon” and seized the leadership in the field of RES.

Energy Efficient Buildings | Clean Power | Changemakers | Business Documentary from 2009

In this episode we look at the home of the future. A gizmo that generates clean power within
your house; a skyscraper combo-glass that insulates from the tropical heat, is self-cleaning – and
actually generates electricity for the building from the sunlight that falls on it; and the professors in Taiwan busy pulling down walls and digging up concrete, making a start on turning the ultra-urban Taipei into a haven for streams and wild plants.

Had enough of eco-doom and gloom? Taking swimming lessons to cope with the rising sea-levels after climate change? This series looks at some of the weirdest climate change projects emerging from Asia. With its ever-increasing emissions comes the huge threat of climate change.
But Changemakers won’t take no for an answer. They’ve been told that Asia is the problem, with its ever-increasing emissions – but they also know that Asia, with its boundless energy and creativity, can come up with the solutions, too. Scientists and activists across all fields of science and technology are coming up with ideas large and small that all make a difference – and can help inspire others the world over.

المدير التنفيذي لشركة Green Energy يتحدث عن أعمال الشركة في منطقة إدلب

شركة Green Energy لإنشاء واستثمار مشاريع الطاقة الكهربائية بكافة أشكالها تأسست عام 2014 في محافظة حلب السورية باسم GE POWER
وتتلخص أعمال الشركة بثلاثة أنشطة رئيسية هي:
1- إنشاء وتنفيذ مشاريع الطاقة الكهربائية.
2- صيانة البنى التحتية للشبكات والمحطات الكهربائية.
3- استثمار وتوزيع الطاقة الكهربائية.
في عام 2019 اندمجت شركة GE POWER مع شركة GREEN FUTURE للاستثمار تحت اسم GREEN ENERGY.
عملت شركتنا مع جميع المنظمات والمؤسسات في الشمال السوري في قطاع الطاقة الكهربائية وإدارتها، رغم الأوقات والظروف الصعبة التي واجهتنا في مسيرتنا.
نفتخر بموظفين لديهم كفاءة عالية ويعملون بروح الفريق الواحد، ونعتز بالثقة الممنوحة لنا من أهلنا والمؤسسات العاملة في المحرر.
نعمل جميعاً بما نستطيع لإعادة إعمار بلدنا، وتوفير الخدمة لأهلنا، وتحقيق مستقبل مشرق بإذن الله.

Michael Moore presents Planet of the Humans, a documentary that dares to say what no one else will — that we are losing the battle to stop climate change on planet earth because we are following leaders who have taken us down the wrong road — selling out the green movement to wealthy interests and corporate America. This film is the wake-up call to the reality we are afraid to face: that in the midst of a human-caused extinction event, the environmental movement’s answer is to push for techno-fixes and band-aids. It’s too little, too late.

Hill TV Response to critics with Jeff, Michael and Ozzie (17min):
FAQ, Discussion Guide, Media:

Removed from the debate is the only thing that MIGHT save us: getting a grip on our out-of-control human presence and consumption. Why is this not THE issue? Because that would be bad for profits, bad for business. Have we environmentalists fallen for illusions, “green” illusions, that are anything but green, because we’re scared that this is the end—and we’ve pinned all our hopes on biomass, wind turbines, and electric cars?

No amount of batteries are going to save us, warns director Jeff Gibbs (lifelong environmentalist and co-producer of “Fahrenheit 9/11” and “Bowling for Columbine”). This urgent, must-see movie, a full-frontal assault on our sacred cows, is guaranteed to generate anger, debate, and, hopefully, a willingness to see our survival in a new way—before it’s too late.
